Résumé :
William G. Whittow, SMIEEE received the B.Sc. in physics from The University of Sheffield, U.K in 2000 and his Ph.D. in
computational electromagnetics in the EEE Department also at Sheffield in 2004. From 2004 to 2012, he was employed as a
Research Associate in the School of Electronic, Electrical and Systems Engineering at Loughborough University, UK. He has
published more than 100 peer reviewed journal and conference papers in topics related to electromagnetic materials, synthetic
dielectrics, wearable antennas, VHF antennas, Specific Absorption Rate (SAR), FDTD, metamaterials, heterogeneous substrates,
embroidered antennas, inkjet printing, electromagnetic compatibility, phantoms and Genetic Algorithms. From 2007 to 2011, he
was the Coordinating Chair of the Loughborough Antennas and Propagation Conference (LAPC). Dr. Whittow was appointed as a
Lecturer in Electromagnetic Materials Integration at the University of Loughborough in 2012. He serves on the technical
programme committees of several IEEE international conferences. He has been asked to give 5 invited conference presentations
and a 4-day invited workshop on bioelectromagnetics.
Previously, Dr. Whittow investigated the effect of metallic spectacles on the specific absorption rate in the head when exposed
to an RF source. In an ongoing collaboration with Prof. Luxey's Group, a GSM antenna has been designed that can be integrated
into a pair of spectacles. This is highly topical as there are currently a number of smart glasses on the market. However, they
currently only have Bluetooth or WiFi connectivity. It is challenging to integrate a high performance antenna into a compact
shape while maintaining the form factor of a pair of spectacles. Furthermore, the antenna is by definition in close proximity
to the head. The head is a lossy object that detunes the antenna and absorbs electromagnetic fields and hence reduces the
antenna efficiency. Dr. Whittow's contribution to this work was to simulate the EM fields that are absorbed inside the head
and hence calculate the allowable power levels in order not to break the ICNRIP and IEEE SAR standards. Our IEEE APWL paper
on this topic was published in 2013 (Vol 12) and is entitled "Feasibility Study of 4G Cellular Antennas for Eyewear Communicating
Devices". This collaboration is ongoing and antenna and SAR measurements have been made and will be published in 2014.
The team is now extended this work on wearable devices to higher frequencies."
